Hi All,
I have a web application, currently we are storing the user details.
Now we wants to store the Thumb Impressions of the users also, for the unique data maintenance.
So, what is the procedure to store these info and how can i retrieve this data to compare(to avoid the duplicates). How should i build the SDK's to implement this process in my website.

And one more concern, is there any issues while inserting the different thumb impression records from the different places at the same time. Is there any chances for the duplicate data.
